A number of potential applications of aluminum foams are being identified and renewed interest in these engineering materials is also reflected by several current research projects. One of the key issues for industrial exploitation of aluminum foams is the development of cost-effective manufacturing strategies facilitating, preferably, net shape production of foams with controlled porosity and cell size, and minimized structural imperfection. Especially, melt route to aluminum foam production based on the foaming agents offer attraction of low cost and the potential for good microstructure. The present paper is focused mainly on foaming agents of melt-foam aluminum such as TiH2 or TiH2-Al mixture. For the purpose of economical manufacturing, we are proposed to hydrogen induced mechanical alloying (HIMA) process. Thermo-physical properties of particles synthesized are compared with conventional methods. Specimens synthesized are characterized by scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), thermo- gravimetry-differential scanning calorymetry (TG-DSC), pressure-composition-isotherm.

The current status of research and development on the nanopowder technologies is reviewed by using literature information analysis. Especially, nanopowders(or ultla fine particles) are one of the most important key materials for the nanotechnology. Because of the extremely small dimensions, a large volume fraction of the element atoms are formed to colloids or nano clusters, and this confers special attributes to these materials. The nanopowders appear to be a great potential for applications - such as drug systems, field emission display(FED), secondary battery electrodes, fuel cells, atomic force microscopy(AFM)/scanning tunneling microscopy(STM) tips, ultra small diodes, hydrogen storage cell, gas sensors, microwave devices, nano capsules, oil absorbers, nano composites etc... in the near future.

The current status of research and development on the nanotechnologies are reviewed by using literature information analysis. Especially, carbon nanotube(CNT) is one of the most important advanced materials for nanotechnology. Because of the extremely small dimensions, a large volume fraction of the carbon atoms are formed to the tubes-single or multi wall tube-, and this confers special attributes to these materials. The CNT appears to be a great potential for applications, such as emitter, field emission display(FED), secondary battery electrode, fuel cell, atomic force microscopy(AFM)/scanning tunneling microscopy(STM) tip, ultra small diodes, hydrogen storage cell, gas sensors, microwave devices, nano capsule, oil absorbers, nano composites, etc… in the near future for CNTs.
